"Nocturnal enuresis is the medical term for bedwetting. Most children wet the bed occasionally or even nightly during the potty-training years. In fact, it is estimated that seven million children in the United States wet their beds on a regular basis. Controlling bladder function during sleep is usually the last stage of potty-training. In others words, it is normal for children to wet the bed while sleeping during that learning process. Bedwetting is typically not even considered to be a problem until after age 7.

Bedwetting in children is often simply a result of immaturity. The age at which children become able to control their bladders during sleep is variable. Bladder control is a complex process that involves coordinated action of the muscles, nerves, spinal cord and brain. In this case, the problem will resolve in time. On the other hand, it may be an indication of an underlying medical condition, such as obstruction of the urinary tract. If bedwetting persists beyond the age of 6 or 7, you should consult your pediatrician."
